Four hundred thousand tins of this baby milk are being recalled by its Japanese makers because of radioactivity.

Meiji Holdings, one of the countries biggest milk producers, says it’s found radioactive cesium in the product. The levels of cesium are within government safe limits. But the firm has launched a voluntary recall.

The product is sold only in Japan, where parents appeared happy with the steps being taken.

“I think there is no need to be concerned because the levels of radiation are below the safety limit. I am personally not worried as the company is already taking action to solve the problem.”

Worries over the safety of food have been a big issue in Japan following the March 11, 2011 earthquake and tsunami that led to the worst nuclear accident in a quarter of a century.

Radiation from the Fukushima Daiichi nuclear plant spread over large areas of northern and eastern Japan.

Meiji says it doesn’t know how the cesium got into the powdered milk, but suspects material from the Fukushima accident is the source.

Every time President Trump rails against the media, he adds millions in market capitalization to The New York Times Company (NYT). So buying a few call options on NYT is virtually certain to pay off. If you’ve never traded options, fear not. I asked my senior analyst, Martin Hutchinson, to describe options so that a kindergartener would understand.
